This Koyo full complement drawn cup needle roller bearing is suitable for applications with high dynamic loads. It has a smaller cross-section than a machined needle roller bearing for use in restricted mounting spaces. The full complement of rollers provides a higher radial load-carrying capacity than caged rollers. The needle rollers are made of through-hardened, high-carbon chromium steel for durability and heat tolerance, and have contoured ends to optimize the distribution of contact stress. This radial needle roller bearing meets ASTM International standard ASTM F2162 for quality assurance, and is used in various applications, such as automotive and truck transmissions, agricultural and construction equipment, pumps and compressors, and two-cycle engines, among others.
Roller bearings use rolling elements to maintain a separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. Roller bearings can be open on both ends (a shaft can pass through) or open on one end and closed on the other. An open end can be sealed or shielded to protect the bearing from solid contaminants and moisture that could reduce its lifespan. If an end is sealed, the sealing component is an elastomer lip that contacts the shaft. If it is shielded, the shielding is a non-contact lip, usually made of metal. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
Koyo Bearings USA manufactures needle roller bearings, bearing assemblies, and needle rollers for automotive and industrial applications. The company, founded in 2009, is headquartered in Canton, OH, and meets International Organization for Standardization (ISO) standards 14001 and TS 16949 for quality assurance.

Koyo has bought Torrington which was original bearing, but quality is still very good.

Quick response, got the four bearings. But is it necessary to pack and send 4 small bearings in four separate sending?
